Hi Sean,

The minimum should be 15 percent mix. If your budget allows you
should try the 20 or even the 30 percent mix, you’ll get better
performance out of your engine.

At the moment im running it on 15% nitro and 20% 0il byron fuel.Will go for
something a bit stronger.Cheers.

I am running my OS32 on 15% nitro and it is capable of doing everything that I have asked of it without any trouble. There is one thing to take into acount if useing a higher percentage of nitro, 20 up. This is that the higher nitro fuel has been known to ware out the O rings in the engine at a faster rate. If your throttle starts to play up and you are constantly having to adjust your mixture check the O rings.

To be honest it is agreed advice at my local flying feild that in a 32 engine anything above 15% nitro is a waste of time unless you are going to add a lot of weight to your heli. But the choice is yours.

good luck,

will take that into consideration,great stuff.
